Sienna has 5 3/4 pounds of grapes. She eats 1/8 pound and gives 2 1/2 pounds to her brother. How many pounds of grapes does Sien

miskamm [114]

The pounds of grapes left with seinna is 3.125 or $\frac{25}{8}$ pounds

<h3>Solution:</h3>

Given that Sienna has $5\frac{3}{4}$ pounds of grapes

She eats $\frac{1}{8}$ pound and gives $2\frac{1}{2}$ pounds to her brother

To find: pounds of grapes left with seinna

We can find the pounds of grapes left with seinna by subtracting the pounds of grapes she ate and pounds of grapes she gave to brother from the total pounds of grapes she had

Pounds of grapes left with seinna = total pounds of grapes - pounds of grapes she ate - pounds of grapes she gave to brother

$\text {total pounds of grapes }=5 \frac{3}{4}=\frac{4 \times 5+3}{4}=\frac{23}{4}$

$\text {pounds of grapes she ate }=\frac{1}{8}$

$\text {pounds of grapes she gave to brother }=2 \frac{1}{2}=\frac{2 \times 2+1}{2}=\frac{5}{2}$

Substituting the values we get,

$\text {Pounds of grapes left with seinna }=\frac{23}{4}-\frac{1}{8}-\frac{5}{2}$

$\text { Pounds of grapes left with seinna }=5.75-0.125-2.5=3.125$

Thus the pounds of grapes left with seinna is 3.125 or $\frac{25}{8}$ pounds

The speed of the current in a river is 6 mph. A ferry operator who works that part of the river is looking to

Morgarella [4.7K]

Answer:

9 mph

Step-by-step explanation:

Let he speed of the boat on the lake is x.

Considering the speed of the current it will take him:

22.5/(x + 6) + 22.5/(x - 6) = 9
2.5 / (x + 6) + 2.5 / (x - 6) = 1
2.5(x - 6 + x + 6) = (x + 6)(x - 6)
2.5*2x = x² - 36
x² - 5x - 36 = 0
x = (5 ± √(5² + 4*36))/2 = (5 ± 13) / 2
x = (5 + 13)/2 = 9 mph (negative root is discarded as the speed should be positive)
